3. Allow the engine to run at 500–700 rpm for the first 10 sec-
onds. Then warm up the engine at low speed and low load.
IMPORTANT! Do not race the engine while it is cold.
NOTE! Generating set engines automatically rev up to the
pre-set engine speed (1500 or 1800 rpm).
Starting the engine in extremely cold
conditions
Preparations must be made to allow the engine to be started in
extremely cold conditions.
Use a winter fuel (a proprietary brand) approved for the prevailing
temperature. This reduces the risk of wax deposits in the fuel in-
jection system. A fuel heater is recommended for extremely low
temperatures.
Use a synthetic lubricating oil of a viscosity recommended for
the prevailing temperature. See chapter “Lubrication system
service”. Synthetic oils can withstand greater temperature
ranges than mineral-based oils.
Preheat the engine coolant with a separate electrical engine
block heater. In extreme cases a diesel engine block heater
may be required. Ask your Volvo Penta service dealer for ad-
vice.
IMPORTANT! Ensure that the cooling system is filled with
antifreeze. See chapter “Maintenance, Cooling system”.
Batteries must be in good condition. Cold reduces battery ca-
pacity. An increase in battery capacity may be necessary.
